LOCKING DEVICE FOR FlLlNG-RECEPTACLES OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 709,844, datedSeptember 23, 1902.

Application filed May 28,1902. Serial No. 109,352. (No model.)

To all whom it THU/y concern:

Be it known that I, DARWIN E. WRIGHT, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Looking Devices forFiling-Receptacles or the Like, of which the following is a description,reference being had to the accompanying drawings and to the charactersof reference marked thereon. 7

My invention relates to an improvement in locking devices both forfiling-receptacles or drawers themselves and for the card rods orsupports for the cards or other devices filed away in the receptacles;and the particular object is to provide in one apparatus mech anism forunlocking simultaneously and in one operation the drawer and card-rod ofa card-index system and to permit of the separate locking of the rod anddrawer, whereby the former may be looked before the latter.

In an application filed by me on the 22d day of May, 1902, Serial No.108,55 l, I have claimed, broadly, a mechanism of the characterdescribed, and the present invention relates to certain details ofconstruction presenting alternative and dilferent arrangements forcarrying outin certain specific ways the broad ideas covered in theformer application, although it will be understood that the presentinvention is not to be limited in all respects to details ofconstruction. In its broadest sense, perhaps, the invention may be saidto be similar to the other in the fact that in both the same means whichoperate the bolt to retract it also retracts the card-rod-locking lever,the parts mutually coaoting and having means to return to normalposition. In the former case, however, the bolt itself in its movementengaged the card-rod-lockin g lever and released it, while in thepresent case they are simultaneously moved, but are independent of eachother, so that they can be independently returned to normal position.

Theinvention therefore consists in the matters hereinafter described,and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a front view of the locking mechanism with the face-plateremoved, showing the parts in position assumed when the drawer andcard-rod are locked. Fig. 2 is a similar view showing the drawer andcard-rod unlocked. In this figure, however, two cardrods are shown, thecard-rod-locking lever being arranged to act in both simultaneously.Fig. 3 is a view similar to Fig. 1 of a modification of-the invention;and Fig. 4. is a view similar to Fig. 3, showing the drawer-bolt andcard-rod unlocked. Fig. 5 is a similar View of another modification.

In the drawings, A represents the back plate of the lock-casing or aportion of the drawer, the front plate being removed.

B is the drawer-bolt,normally pressed outwardly by the spring 1, bearingagainst the shoulder 2. The bolt is guided vertically by the pin andslot 3 4. It is offset to form a downwardly-depending arm 0, which atits lower end has a projecting shoulder 5, against which, as shown inFigs. 1 and 2, one side of a double key 6 is adapted to bear to depressor retract the bolt to unlock it. Where the offset takes place ashoulder 7 is formed, over which when the bolt is retracted ordepressed, as shown in Fig. 2, the upper end 8 of a swingingspring-catch D is adapted to fit, thus holding the bolt in retractedposition until released by swinging the catch from engagement with theshoulder 7, which is accomplished by the operator grasping the pin 9 onthe lower end of the catch D, projecting through the slot 10, and movingit to the position shown in Fig. 1. At the same time that one side ofthe key presses upon the upper side of projection 5 it bears against thelower side of projection 11 on the cardrod-locking lever E,which isvertically guided by pin-and-slot arrangement l2 l3 and has a projectingarm 14 at it lower end normally bearing by spring 15 on the card rod F.When the locking-lever E is raised or retracted, as shown in Fig. 2, theupper end 16 of a swinging spring-catch Gr engages beneath the shoulder17 and holds the lockinglever out of engagement with the card-rod untilcatch G is swung by means of pin 18, projecting through slot 19, toposition shown in Fig. 1. As shown in Fig. 2, the arm let extends inopposite directions and serves to engage and lock two card-rods insteadof one, as shown in Fig. 1.

In Fig. 3 a key with one arm instead of two arms is used, and this isadapted to bear on the projecting end 21 of a freely-swinging lever H,having a shoulder or projection 22 to engage the under side of theprojection 11 on the card-rod-locking lever E and having on its oppositeend a shoulder 20 to engage the upper side of the projection 5 on thelocking-bolt 0. Thus there is a pivoted lever 11, adapted in itsmovement under the action of the key to simultaneously retract the boltand card-rod-locking lever; but as it is freely pivoted when thepressure of the key is Withdrawn it allows sufficient play between theshoulders 20 and 5 and 22 and 11 as to permit the independent expandingmovements of the bolt and card-rod-locking lever when the spring-catchesD and G (which correspond to D and G in Figs. 1 and 2) release the saidbolt and locking-lever.

In Fig. 5 still another modification is shown, which is to a certainextent a combination of Figs. 1 and 3 in that the swinging lever Hisattached to the bolt-shank to have a slight lateral play by means of thepin and slot 2; 25, and as the bolt is depressed through the action ofthe key, which may be single or double, the outer end of the lever Hengages the projection 26 upon the card-rod-locking lever E and raisesthe same, the catch G passing under the shoulder 17 and holding thelocking-lever out of engagement with the rod. The other parts of themechanism correspond to the parts shown in other figures of thedrawings.

It will he understood that the arrangements shown in Figs. 3, 4, and 5may be applied to looking a plurality of card-rods simultaneously.

Various minor modifications and changes may be made without departingfrom the spirit of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a card-indexing system or similar filing apparatus, a lockingdevice for the receptacle, a card rod or support, and means for lockingthe same, means for unlocking at one operation both the receptacle andthe card rod or support, and means for returning the devices to lockingposition independently of each other; substantially as described.

2. In a card-indexing system or similar filing apparatus, a lockingdevice for the receptacle, a card rod or support, and means for lockingthe same, means for simultaneously unlocking both the receptacle and thecard rod or support, and means for returning the devices to lockingposition; substantially as described.

3. In a card-indexing system or similar filing apparatus, a lockingdevice for the receptacle, a card rod or support, and means for lockingthe same, means for simultaneously unlocking both the receptacle and thecard rod or support, and independently-operated means for returning thedevices to locking position; substantially as described.

A filing-receptacle having a locking-bolt, a card rod or support, anda locking-lever therefor, a pivoted lever connecting the locking-boltand locking-lever, means for operating the pivoted lever to retract thelocking-lever in one operation with the bolt, and means for releasingthe bolt and locking-lever; substantially as described.

9. A filingreceptacle having a locking-bolt, a card rod or support, anda locking-lever therefor, a pivoted lever normally engaging thelocking-bolt an'd locking-lever, means for operating the same to retractthe bolt and locking-lever, and means for releasing the bolt andlocking-lever; substantially as described.

10. A filing-receptacle havinga locking-bolt, a card rod or support, anda locking-lever therefor, a pivoted lever normally engaging thelocking-bolt and locking-lever, means for operating the same to retractthe bolt and locking-lever, catches for holding the bolt andlocking-lever retracted, and means for operating the catches to causethem to release the bolt and locking-lever; substantially as described.

In testimony whereof I aifix my signature in presence of two witnesses.
